the Heisenberg-Weyl group connected with Heisenberg commutation relations [1], the Pauli spin matrices [2] used in generalized angular momentum theory and theory of uni- tary groups, and the pairs of Weyl [3] of relevance in finite qu antum mechanics.

But we have four Dirac operators and only three Pauli operators. Thus we study a system where we have two independent spins, one with the spin operator σ and another one with spin operator ρ.

25 Oct 2018 and B2 are eigenvectors of the Pauli matrices σ1, σ2 and σ3 (defined They satisfy the commutation relations [x, px]− = i, where is the Planck. 11 Aug 2020 This so-called Pauli representation allows us to visualize spin space, and also A general spin operator A is represented as a 2×2 matrix which the σi satisfy the commutation relations =2iσz,[σy,σz]=2iσx,[σz,σx]=2iσ The Pauli matrices obey the following commutation and identity matrix. The above two relations can be summarized as: Eigenvectors and eigenvalues 1.1; Pauli vector 1.2; Commutation relations 1.3; Relation to dot and cross product 1.4; Exponential of a Pauli vector 1.5  i = 2ij. (10.113). The Pauli matrices divided by 2 satisfy the commutation relations (10.97) of the rotation group.
